However, the concrete dustpan produced by using the mold can only apply external force to the concrete dustpan in a mode of knocking the mold body, so that the dustpan product can be separated from the mold body. In such an operation, if the water dustpan product is demolded at the theoretical time node of 24 hours, the water dustpan product is knocked, so that the damage such as surface depression, marks, cracks and the like is easily generated in the subsequent drying shrinkage process of the water dustpan product, and the rejection rate of the water dustpan is high.

Therefore, in the actual production process, the mould is used for production, and the concrete dustpan is required to be completely dried and contracted in the mould until the volume is minimum (the waiting time is about 72 hours), and then the mould is knocked around to demould; however, the concrete dustpan loses the opportunity of maintenance due to the operation, the quality of products is easy to be inconsistent with the standard, the defective rate is high, and the turnover rate of the die is low due to long waiting time.
